During the Christmas party in her apartment, Joyce Stone welcomes the stepbrothers Helena Monet and Alex Monet, who is her boyfriend. Alex's best friend asks him to demonstrate his abilities of scanner and during his demonstration, Alex is distracted by a guest
and accidentally kills his friend. Alex is considered non-guilty but decides to travel to a monastery in Thailand to learn to control his powers. Two years later, Joyce and Helena are attacked by a gang in an alley and Helena activates her ability of scanner
to save them. She has a severe migraine associated to the sound of voices and her stepfather Elton Monet shows an experimental EPH-3 patch that he is developing in his company to be used in scanners. Helena offers to be the guinea pig, but he does not accept
the offer since he is still studying the side effects. During the night, Helena opens his wallet and secretly uses the EPH-3. Immediately her migraine disappears and she feels good; however her personality changes to an evil person. She humiliates her boss
Mark Dragon, who is the owner of the TV network where she works, and later she destroys him to assume the control of the television; she kills Elton to assume the control of his company and research; she kills Dr. Baumann, who conducted painful experiments
on her when she was a teenager. Meanwhile Alex's lawyer and friend Michael travels to Thailand to warn Alex about the changes in Helena but he is murdered by a scanner sent by Helena to follow him. The Monk gives a final training to Alex and he returns home.
Will Alex succeed to control Helena? A young female scanner turns from a sweet young thing into a murderous, power-crazed villain after she takes an experimental drug developed by her father. Her brother, who is also a scanner, is the only one powerful enough
to stop her. This movie is misunderstood. It caters to a very specific audience that enjoys seeing power abused to create injustice. Much like other movies of this type, much of the movie focuses on the main villain. The villain uses their disproportionately
powerful abilities for pleasure and profit. People who look too deep into the plot will be disappointed for they didn't grasp that the movie is a pornography for power, affluence, and domination.

If you enjoy seeing people struggle from the overpowering supernatural abilities of an immoral female protagonist disguised as an antagonist, then this movie is definitely for you. There are very few like it, and in that sense, this movie is a gem. Other movies
that resemble to this on are Supergirl, Stardust, I Dream of Genie, Zap 3, and Matilda. All of which had a poor score because most didn't understand what the target audience was. A young female scanner turns from a sweet young thing into a murderous, power-crazed
villain after she takes an experimental drug developed by her father. Her brother, who is also a scanner, is the only one powerful enough to stop her.

We start out with the standard good and evil plot, brother against sister... but, in all fairness, this is a plot structure that works. From there, it actually gets much more creative, introducing the use of Eastern meditation to control the scanning and the
use of TV to more widely broadcast scanning.

Some memorable moments are here, too, including the mind-control dance scene, the Taiwanese boxing and plenty of firefights and explosions, including an arm that flies off.

As with "Scanners II", this definitely could have been a series, even more than the last film. The ideas developed here really set up a broader picture of good scanners against bad ones, and how such powers could be used not just on a combat level, but to actually
infiltrate and dominate society. There is much potential.
